Use correct error value in Token Exchange error responses

The Token Exchange [RFC8693 Section-2.2.2](https://datatracker.ietf.org/doc/html/rfc8693#section-2.2.2) requires
that the error code for invalid requests is `invalid_request`.
Previously, Keycloak used `invalid_token` as the error code.

Fixes #31547
